GLOBE HOLDER Filed July 15, 1930 Patented Oct. 27, 1931 UNITED STATESPATENT OFFICE PAUL J'. PFEIFER, OFGLEVELAND' HEIGHTS, OHIO, ASSIG-NOR TOTHE JOHN C. VIRDEN COMPANY, OF CLEVELAND, (PI-I10, A CORPORATION OF OHIOGLOBE HOLDER application filed July 15,

This invention relates to globe holders, and more particularly to meanscarried by devices of this character for detachably retaining globes andthe like.

It is an object of the present invention to provide a spring biasedretaming device which is constructed and arranged to operate'with aminimum flexing of the spring, whereby crystallization or fatigue of the19 metal is avoided, and the life of the spring prolonged.

A further object of the invention is to pro: vide a recess to receivethe retaining device in inoperative position, to increase the clearancefor installing the'globe or the like.

Other objects and features of novelty will be apparent as thefOllOWihgdGSCllptlOn proceeds, reference being had to the accompanyingdrawings in which Figure 1 is an elevation of a globe holder accordingto the preferred embodiment of the present invention, showing a portionof the globe, and parts of the view be ng broken away to show internalconstruction;

Referring more particularly to the drawings, the globe holder 10 may beof any desired construction or shape, preferably a cupshaped sheet metalmember formed by stamping or spinning a fiat sheet to form a pleasingcontour. The sheet metal is preferably brass but obviously other metalsmay be used for this purpose. The top of the holder 10 may be providedwith supporting and win 45 ing apertures 11 and 12, and the lowerportion of the inverted cup is provided with a flat, radial flange 13and a depending annular flange 14 terminating in a rolled rim or bead15.

The globe holder is adapted to support a 1930. Serial No. 468,002.

globe 16 which is provided with a flange or bead 17. Accordingly, theglobe holder is provided with spaced abutment members 18 and a latchingmechanism 19. The globe is inserted in the globe holder with the portion17 in abutting relation with the abutments 18 and the latching mechanism19 operated-to engage the other side of the portion 17 and thus hold theglobe in the globe holder.

T he abutments 18 are preferably strips of a sheet metal, such as brassor other metals which are inherently pliable, or are annealed for thispurpose. The strip of sheet metal is rolled or bent as at 20 to form thedesired abutment, and secured inside the holder 10, as by rivets 9. Thisconstruction is of advantage in that the abutment 18 may be manuallyvaried. The roll 20 may be gripped by pliers and permanently compressed,to thus provide a larger opening to receive the portion 17, or the rollmay be spread or bent inward to decrease the opening. The portions 17may vary considerably in diameter for globes of approximately the samesize, and this expedient affords a very simple means for taking care ofthis variation.

The latching mechanism 19 includes a spring 21 which is secured insidethe globe holder by means of a rivet 22. The spring 21 terminates in anotched end 23 which lies within the corner 24 formed by the flanges 13and 14. Interposed between the end 23 and the corner 24 is a retainingmember 25, best shown in Fig. 5, as comprising a rigid memher having adepending arm 26 and a shorter lateral arm 27. The portion 27 is adaptedto lie between the end 23 and the flange 13, with the portion 26depending adjacent the flange 1 1. The corner 28 of the member 25 fitsin the notch of the end 23 and the spring 21 urges the corner 28 intothe corner 24.

The flange 1a is preferably pressed out wardly to form an inwardlyfacing recess 29 above the head 15. A slot 30 extends transversely ofthe portion 29 just above the head 15 and is adapted to receive anoperating member 31, best shown in Fig. 5. The member 31 comprises ahead or cam portion 32 which is adapted to lie between the dependingportion 26 of the retaining member 25 and the inner wall of the flange14 at the pocket 29.

The member 31 also comprises an extension 33 which is of reduced width,forming shoulders 34. This extension is passed through I 5 the slot 30,so that the shoulders 34 rest against the flange'le within the pocket 29and above the bead 15, thus forming a pivotal mounting for the operatingmember 31. e

'In operation, assuming that a rough adj ust ment of the rolled portions20 has been made to suit the globe portion 17 of'the globe be-cving'installed, the operating arm 33 will extend radially through theflange 14, and thus the portion 32 will lie within the pocket 29 underthe depending portion 26 of the operat ing member 25, which will also Ibe housed within the pocket 29. Thisarrangementpermits the latchingmechanism'to clear the globe bead 17 as the. same is inserted into theflange 14. The operating arm 33 will then move upwardly, causing the camportion 32 to move inwardly and cam the depending portion 26 oftheretaining member 28 into engagement withthe outside of the globe bead17, 'When the arm 33 completes its movement and lies snugly against theoutside of the flange 14, the camportion 32 has'passed dead center, andthus the latching mechanism has a snap action which holds it in latchedposition. The inward movement of theportion 26 causes a downwardmovement of the corner 28 and consequent downward movement of the springend 23'. This arrangement is important as it will be noted thatthe totalmovement of the spring end 23 is much less than the total "movementofthe lower end of the portion 26. The provision of adequate latchingaction with a very small movement of the portion 13 and consequent 40slight flexing of; the spring21 serves to prolong the-life of thespring'inasmuch as the liability of crystallization or fatigue of themetal of the spring is reduced to aminimum.
